The one thing we felt was missing from Nokia's Windows Phone line up was a big screen monster, and this feeling was emphasised when we knew the US was enjoying exactly that - the Lumia 900 and its 4.3-inch AMOLED display.

Luckily for us, the Lumia 900 finally arrived in the UK in May, bringing with it a front-facing camera, more of that excellent Nokia sturdiness and Windows Phone Tango.

Aesthetics

The first thing you will notice is the sturdy, chunky design Nokia has bestowed the Lumia 900. You will then notice it's a chunky beast - 160g, to be precise. Make no mistake, you don't forget this smartphone is in your pocket, which is both good and bad. Good, because you will struggle to forget it. Bad, because it weighs you down a tad.

This is in part down to that big-old display. It's 4.3-inches in size, and unlike the Lumia 800's display, it's completely flat - and looks better for it.

At the bottom are the traditional three buttons found on any Windows Phone. From left to right, you have a back button, which also deals with multi-tasking if you press and hold it, the home button and a search button for quickly bringing up Bing. On the right side sits a volume rocker, lock/unlock and a camera button.

These buttons have been adjusted so they are more easily reachable. Volume, for instance, now sits much further down from the top, providing more comfortable ergonomics.

Other improvements over the Lumia 800 include the removal of that plastic cover for the microUSB slot. This is handy because, once broken, the gap it leaves looks odd. It's also more accessible. Sadly, anyone who uses a dock will still have to endure the Lumia 900 upside down - the speaker sits at the bottom instead. And you will need a supplied pin to access your microSIM-card, in iPhone style.

Hardware

Any anti-Windows Phone fan will say something about single core processors and bad performance, and they would be right on one count. A 1.4Ghz processor does feature in the Lumia 900 as it did the Lumia 800 and the 710 before it. Where they are wrong, though, is in the performance assumption.

Having used Windows Phone since its launch, we've yet to complain about speed except in the instance of the Lumia 610, which has incredibly low specs.
